•Materials of Bearings
Materials for bearing rings and parts largely determine the bearing's performance and life. LYAZ Bearings puts more efforts to select materials for bearing ring and part suppliers in a rigorous manner.
Materials and components of bearing rings for LYAZ Bearings are provided by the world's top suppliers,especially for serving bearing manufacturers, fundamentally solving the issue that our bearings lag behind imported bearings in terms of materials for a long time.
LYAZ Bearings boasts a set of strict incoming goods inspection system. Before being put into storage, every batch of steels and parts is under systemic inspection, including analysis of material composition, metallographic analysis, accuracy check, assembly test, etc.
 
•Materials for Bearing Ring and Roller Body
Bearing ring and roller body are mainly made of high-Cr bearing steel. Listed below are compositions of material for bearing ring and roller body.

Material for bearing ring and roller body mainly consists of high C-Cr bearing steel.
 
•Material of cages
Material of cages need good wear resistance, stable size and metal strength. Therefore, operation environment should be mainly considered in selection of material of cages.
 
Cold-rolled Steel Cage
These light cages hold a high strength with reduced friction and wear in an effective way after surface treatment. The following table covers compositions of material for cold-rolled steel sheet.

Brass Cage
Brass cage is adopted in small and medium bearings. However, brass cage is not suitable for compressors with ammonia cooling due to potential seasonal cracking of brass. It is recommended to replace it with iron cage.
Nylon cage
According to the type and usage of bearings, nylon cages are widely adopted, but they are inappropriate for environments where the temperature is above 120ºC or below 40 ºC. Most of cast molding cages adopt nylon PA66 material, with or without glass fiber reinforcement whose advantage is a good combination of strength and elasticity.
 
•Materials for Dust Shield and Sealed ring
 
Material for dust shield
LYAZ Bearings use cold-rolled tin plate as the standard mateiral for dust shields, but also use stainless steel of AISI-300 specification sometimes.
 
Material for seal ring
Seal rings are mainly made of NBR. For high temperature, fluoro rubbers and silicon rubbers are widely used as well.
